Title: Radiant heat type drying apparatus
Inventor: UJI YUKIO
IPC: B29B15/12
Filed: 1986-10-30
Abstract: PURPOSE:To make large amt. of a heat-insulating material unnecessary and to reduce heat radiation from the rear face of a radiant heat panel, by setting a hot air returning duct sending back hot air introduced into the radiant heat panel in a drying oven along a face of an opposite side to a face of the radiant heat panel facing a resin-impregnated sheet. CONSTITUTION:Hot air is introduced into a radiant heat panel 3 from an air supplying hole 11 through an air supplying duct 8 by means of a circulating fan 6 and a radiant heat is generated on the surface of the radiant heat panel 3 by using this hot air as a heat source to heat and dry a resin-impregnated sheet 1. The hot air in the radiant heat panel 3 is transferred into a returning duct 4 through a through-hole 12, exhausted into an exhaust duct 14 from an exhaust hole 13 and returned to the circulating fan 6. Because the returning duct 4 is set along the rear face side of the radiant heat panel 3, the rear face side of the radiant heat panel 3 can be kept warm with the hot air passing through the rear side and to keep the generation of radiant heat from the surface side. It is thereby possible to reduce the used amt. of a heat-insulating material to be filled into the drying oven 2.

Title: Adjusting method of wavelength of emitted light
Inventor: OMI KAZUAKI
IPC: H01L21/205
Filed: 1987-10-14
Abstract: PURPOSE:To adjust the wavelength of emitted light readily with light emitting intensity being kept, by changing the composition ratio of group IV elements constituting fine particles of a light emitting member. CONSTITUTION:SiH2 gas is sent in through a gas introducing port 12. Plasma is generated in a reaction chamber 5, and the gas is decomposed and made to react. Thus fine particles are formed. The fine particles are blown out through a contracting and expanding nozzle 1 together with gaseous active species, part of which is not reacted. The fine particles are blown on a substrate 6 and fixed. One or more kinds of gases including group IV elements are mixed, and fine particles are formed by the same way. The composition of the fine particles, which are formed in correspondence with the mixing ratio of the gases and optical bandgaps are changed. Therefore, the wavelength of the emitted light can be controlled readily. The intensity of the emitted light becomes very intense.

Title: Forming method of multilayer interconnection
Inventor: ISOBE AKIRA
IPC: H01L21/768
Filed: 1985-11-18
Abstract: PURPOSE:To improve integration density and to obtain a multilayer interconnection without decreasing the thickness of an insulating film on an neighboring wiring, by providing a through hole, whose lower part is a columnar shape and opening part is slanted, thereby decreasing the breakdown of the second wiring layer at the step part of the opening part of the through hole, and decreasing side etch. CONSTITUTION:On an insulating film 2, which is formed on a silicon substrate 1, a first aluminum wiring 3 is formed. Then, spin coating of a polyimide front body is performed. Then burning is performed and a polyimide film 4 is formed. Thereafter, the spin coating of the polyimide front body is performed again and burning is performed. Thus a polyimide film 5 is formed. Thereafter, a through hole is formed by anisotropic dry etching. Then heat treatment at 450 deg.C, which is similar to the heat treatment of the polyimide film 4 is performed. Then, a slanted part is especially formed at the opening part of the polyimide film 5. Thus the through hole, whose opening part is gentle, is formed. At this time, however, the heat treatment of the lower polyimide film 4 was already finished at 450 deg.C. Therefore the decrease in insulation withstanding voltage due to the reduction in thickness of the insulating film on the neighboring wiring layer caused by the slant part as in a conventional example is not yielded.

A switching element Q1 of the step-up-and-down type converter circuit 3 is controlled by a computing control circuit 6 so that the sinusoidal waveform of the input current is maintained and that the constant power output is obtained. This constant power direct current output is converted to the low frequency at about 100Hz-300Hz, and supplied to output terminals (u), (v).
